Ectoedemia spinosella mine

Prunus spinosa, Wrakelberg; leg Diersystematiek VU

mine

Egg at the underside of the leaf, usually near the midrib, sometimes a side vein or the leaf margin. The first part of the mine is a narrow gallery, almost completely filled with reddish frass; the corridor is strongly contorted, almost forming a secondary blotch. The continuation is somewhat less contorted, and here the frass leaves clear margins. Finally the corridor widens into a rather small elongate blotch, where much of the copious frass is compacted in the basal section. The mine is compressed in a limited space, and the final blotch often obliterates earlier parts of the mine.

hostplants
